# Description:
#   This file contains python code that asks the user for
#   their major and grade, and prints out whether they are
#   eligible to move on to CMSC 202 in the next semester.

#   This version uses logical operators rather than
#   nested decision structures.

def main():

    # get major and grade from the user
    major = input("Please enter your major: ")
    grade = input("Please enter your grade: ")

    # for everyone, an A or B counts as passing the class
    if grade == "A" or grade == "B":
        print("You can take CMSC 202!")

    # use PARENTHESES to ensure that the parts of the
    # conditional are evaluated in the correct order
    elif grade == "C" and (major == "CMSC" or major == "CMPE"):
        # for CMSC and CMPE majors, a C is not enough to pass
        print("You cannot move on to CMSC 202.")

    # note that the OR for majors used above switched to an AND instead
    # they cannot be a CMSC major *AND* they cannot be a CMPE major
    elif grade == "C" and major != "CMSC" and major != "CMPE":
        # for all other majors, a C is enough
        print("You can take CMSC 202!")

    # any other grade does not count as passing, regardless of major
    else:
        print("You cannot move on to CMSC 202.")
